Abstract
Glioblastoma multiform (GBM) remains clinical indication with significant “unmet medical need”. Innovative new therapy to eliminate residual tumor cells and prevent tumor recurrences is critically needed for this deadly disease. A major challenge of GBM research has been the identification of novel molecular therapeutic targets and accurate diagnostic/prognostic biomarkers. Many of the current clinical therapeutic targets of immunotoxins and ligand-directed toxins for high-grade glioma (HGG) cells are surface sialylated glycoproteins. Therefore, methods that systematically and quantitatively analyze cell surface sialoglycoproteins in human clinical tumor samples would be useful for the identification of potential diagnostic markers and therapeutic targets for malignant gliomas. In this study, we used the bioorthogonal chemical reporter strategy (BOCR) in combination with label-free quantitative mass spectrometry (LFQ-MS) to characterize and accurately quantify the individual cell surface sialoproteome in human GBM tissues, in fetal, adult human astrocytes, and in human neural progenitor cells (NPCs). We identified and quantified a total of 843 proteins, including 801 glycoproteins. Among the 843 proteins, 606 (72%) are known cell surface or secreted glycoproteins, including 156 CD-antigens, all major classes of cell surface receptor proteins, transporters, and adhesion proteins. Our findings identified several known as well as new cell surface antigens whose expression is predominantly restricted to human GBM tumors as confirmed by microarray transcription profiling, quantitative RT-PCR and immunohistochemical staining. This report presents the comprehensive identification of new biomarkers and therapeutic targets for the treatment of malignant gliomas using quantitative sialoglycoproteomics with clinically relevant, patient derived primary glioma cells.

Abstract
Malignant astrocytic brain tumors are among the most lethal cancers. Quiescent and therapy-resistant neural stem cell (NSC)-like cells in astrocytomas are likely to contribute to poor outcome. Malignant oligodendroglial brain tumors, in contrast, are therapy sensitive. Using magnetic resonance imaging (MRI) and detailed developmental analyses, we demonstrated that murine oligodendroglioma cells show characteristics of oligodendrocyte progenitor cells (OPCs) and are therapy sensitive, and that OPC rather than NSC markers enriched for tumor formation. MRI of human oligodendroglioma also suggested a white matter (WM) origin, with markers for OPCs rather than NSCs similarly enriching for tumor formation. Our results suggest that oligodendroglioma cells show hallmarks of OPCs, and that a progenitor rather than a NSC origin underlies improved prognosis in patients with this tumor.

Abstract
In the central nervous system, neuron generation continues throughout adulthood. This neurogenesis is involved in a continual adaptative process in relation with the environmental complexity. It decreases with age and is reduced in several types of experimental conditions mimicking stress, depression, addiction and neurodegenerative diseases. It may be enhanced after excitotoxic, ischemic or traumatic injuries suggesting a compensatory adaptative response. Available data on this new concept in the field of neurosciences and possible therapeutic relevance are reported.

Abstract
Environmental risk factors such as stressful experiences have long been recognized to affect seizure susceptibility, but little attention has been paid to the potential effects of improving housing conditions. In this study, we investigated the influence of an enriched environment on epileptogenesis. Epileptic susceptibility was assessed in animals housed in an enriched environment either before and during (group I) or only during (group II) a kindling procedure and in animals placed in isolated conditions (group III). The kindling paradigm provides a reliable assessment of the capacity to develop seizures following repeated daily low-frequency electrical stimulations. As both enriched environment and seizures are known to interfere with hippocampal neurogenesis, the number of newly generated dentate cells was assessed before and after the kindling procedure to investigate in more detail the relationship between epileptogenesis and neurogenesis. We found that susceptibility to developing epilepsy differed in animals housed in complex enriched environments and in those housed in isolated conditions. Kindling epileptogenesis occurred significantly later in animals housed in enriched conditions throughout the procedure (group I) than in animals from groups II and III. We also demonstrated that cells generated during kindling survived for at least 42 days and that these cells were more numerous on both sides of the brain following environmental enrichment than in rats housed in isolated conditions. As similar values were obtained regardless of the duration of the period of enrichment, these cellular changes may not play a major role in delaying kindling development. We suggest that the increase response in neurogenesis following seizures may be an adaptative rather an epileptogenic response.

Abstract
Prior epileptic episodes have been shown to decrease markedly the neuronal damage induced by a second epileptic episode, similar to the tolerance following an episode of mild ischemia. Endogenous neuroprotective effects mediated by various mechanisms have been put forward. This study investigated whether neuroprotection against the excitotoxic damage induced by re-exposure to an epileptic challenge can reflect a change in epileptic susceptibility. Tolerance was elicited in rats by a preconditioning session using intrahippocampal kainic acid (KA) administration followed at 1, 7 and 15-day intervals by a subsequent intraventricular KA injection. The degree of pyramidal cell loss in the vulnerable CA3 subfield contralateral to the KA-injected hippocampus was extensively reduced in animals experiencing KA ventricular administration. This neuroprotection was highly significant 1 and 7 days after injection, but not 15 days after injection. In preconditioned animals, the after-discharge threshold was assessed as an index of epileptic susceptibility. It increased significantly from 1 to 15 days after intrahippocampal KA administration. Finally, an enhancement of neuropeptide Y expression in both non-principal cells and mossy fibers was detected, occurring at the same time as the decrease in epileptic susceptibility. These results provide further evidence of an 'epileptic tolerance' as shown by the substantial neuroprotective effect of a prior episode of epileptic activity upon subsequent epileptic insult and suggest that the prevention of excitotoxic damage after preconditioning results from an endogenous neuroprotective mechanism against hyperexcitability and seizures.
